Initial sightings:
Front has extended shackle with stock springs. No good. The shackles look weak and they hurt your pinion angle. I recommend you either put it back to stock (shackle) or investigate a good lift spring and all that goes with that. Your shocks aren't hooked up. My guess is they are factory length and just can't reach with the longer shackles.
Rear blocks aren't ideal, but not a deal breaker. The good news is that if you choose to go back to stock height, it would appear to be pretty simple. Also noticed your driver's rear bump stop (on frame) looks bent/twisted. It could also be just a photo illusion or the truck isn't level, but you might want to check out the frame around the area for damage. Might just be a bent bumpstop or could be signs of frame damage.
I will say, we've all seen far worse starting points. With a plan and a little work (and actually not much $) you could have the suspension back in good running (stock condition) pretty easily. Same thing if you wanna lift it properly, just add $.
Thank you! I knew the shocks weren't bolted up and figured that was the reason why. I'm also glad that it can go back to stock ride height easily. I was starting to like the lift, but safety is my #1 priority since my two boys will be riding in it. So I'm on the lookout for a set of shackles and Chevy truck rally's!
